Beyonce is Now "Sasha Fierce"

Beyonce Knowles now joins an ever-growing list of singers who have changed their names; she is going from Beyonce to Sasha Fierce. Coincidentally, this move coincides with her new album, 'I Am...Sasha Fierce,' which will be out November 18.

Beyonce is such a cool name, so why the change? Here's what Beyonce/Sasha Fierce has to say about it: "Sasha Fierce is the fun, more sensual, more aggressive, more outspoken side and more glamorous side that comes out when I'm working and when I'm on the stage."
